Postman

Notes on Postman for APIs.

A GET request is for consuming data from the API.

A POST request is for writing data to the API.

Best practice is to send data in the body of the request, which a normal web browser won't let you do, thus you install Postman.

Postman is nothing more than a web browser, but on steroids, so it can expose a lot more functionality than a normal web browser.
